ST75ZF is ok and the price now is RM490. However this is not a modular PSU

At the same time, I'd prefer the Decathlon series or Corsair's HX620.

Good stuff Where did you got it from and how much?

ST56F should be sufficient for that setup.

Actually I don't really understand the question More explanation needed?

What PSU are you using?

I think in the days to come, most of us would be using 1kW PSU's considering the fact that newer graphics card eats up more power I thought they are suppose to go green, save energy and consumption.

The price will eventually drop 5-6 years ago, I bought an Antec TruePower 350W for RM400
In fact the 800W Gigabyte Odin is a good buy

It's true that energy efficient is the focus these days. I'm not sure about the 3870X2 (not being an ATI fan for a while) but I know the 9800GX2/GTX takes more power than it's predecessor so we can only guess how it would be moving forward. If we want a 9800GX2 SLI, we'll definitely need a powerful PSU.

Acbel series of PSU or top up a bit more to get something decent at RM200+

As long as you get a PSU made by one of the reputable brands then it would be alright

Most importantly, get something adequate for what we have in the rig. If it's a normal setup, those Acbel 390W is alright. Don't forget there are many people using Icute and still live with it for years

Can I recommend you the Gigabyte Odin 550W? It's slightly more expensive than the ST56ZF but comes with black sleeved modular cables

First of all, look at what you intend to run on that rig. A normal setup with 8800GT would still survive with a 500W-550W PSU. Secondly, get a reputable branded PSU. Don't get something you've never heard and read some reviews before you buy.

I normally don't go to the details of the ripple effects, current, etc. To me, these are just extras that are ignorable but what's important is a PSU which is adequate enough to power the rig (with some extra room for upgrade later) from a reputable make. However, I do agree that for the setup you've mentioned, 300W is enough.

If you read the reviews (JonnyGuru), the Mushkin isn't doing that well and Corsair still does it better.

It's still usable but for people that would measure everything and read reviews, they would remove this PSU from their buy list I have a friend using a Mushkin for nearly a year with 2900PRO without problems. So far, nothing has died in his rig. I have to agree that for enthusiasts, everything matters

It's usable but with the money, you can have other choices

They are all +/- about the same, pros on cons. The Corsair HX620 has nice modular cables though - something I'd like to have

You're comparing a 600W and a 450W, of course there'll be a big difference. If you compare 600W and 620W then it's not that huge.

My rig is very similar to your setup and I'm running on a Gigabyte Odin 550W. Since PSU is cheap these days, you might also want to consider the Corsair HX620 with some extra room for power.

You should do a one time investment because if you sell and buy the HX620, you'll lose the money unnecessarily. I like that HX620 but no point changing since I got the Odin 550W already. I'll keep it for some time since it's good enough for now.
